Design and Development of Jigs for Assembly of Wooden Pallets : Case Study of Latthasit Part., Ltd.

Abstract

Design and development of jigs for the assembly of wooden pallets. The objective is to determine the inclination angle of jigs for assembly and reduce the number of employees assembling wooden pallets. Jigs for the assembly of wooden pallets. Width 1,200 mm., length 1,200 mm., height 200 mm. The position and angle of the clamp can be adjusted to suit the production of 2 types of wooden pallets: beamed wooden pallets and block-type wood pallets. In assembling wooden pallets with beams and wooden pallets with block-type wood pallets, one worker was used to adjust the position according to the drawings. Adjust the jig tilt angle from 50 to 60 degrees and collect the experimental results. The results showed that the angle of inclination of the gripping device and the type of wooden pallets affect the time in the wooden pallet assembly process. As follows, the assembly of wooden pallet beams reduces the number of staff to 1 person. The average minimum assembly time is 2.26 minutes per piece by adjusting the inclination angle of 55 degrees. It takes 0.31 minutes more than assembly time without traditional equipment but can reduce costs. Increase profits by 30,277 baht per month. As for the assembly of wooden pallets, the block type is reduced to 1 worker. The average minimum assembly time is 5.52 minutes per piece by adjusting the inclination angle of 55 degrees. It takes less time to assemble than without assembly. Traditional equipment is 0.58 minutes per piece but can reduce costs and increase profits by 35,133 baht per month.
